The European Union has passed the milestone of 100 gigawatt (GW) of installed wind power capacity, according to the European Wind Energy Association (EWEA).

100 GW of wind power can generate electricity over a year to meet the total consumption of 57 million households, equivalent to the power production of 39 nuclear power plants.

It took the European wind energy sector some twenty years to get the first 10 GW grid connected. It only needed 13 years to add an additional 90 GW. Half of the total European wind power capacity has been installed over the past six years.

"It would require burning 72 million tonnes of coal annually in coal fired power plants to match Europe's annual wind energy production. Loading that amount of coal on trains would require 750,000 wagons with a combined length of 11,500 kilometres - the distance from Brussels to Buenos Aires, Argentina," said Christian Kjaer, CEO of EWEA.

"Despite only utilising a tiny fraction of Europe's vast domestic wind energy resources, wind power is having a substantial impact on Europe's energy security and environment, and benefits us hugely in creating green jobs and technology exports", said Kjaer.

• Anholt offshore wind farm, 400 MW developed by DONG off the coast of Denmark;• Linowo, 48 MW developed by EDF Energies Nouvelles Polska in Poland;• Ausumgaard, 12 MW developed by a private landowner in Denmark (west Jutland); • Akoumia, 7.2 MW developed by Greek power company PPCR on the island of Crete.

To produce the same amount of electricity as 100 GW of wind turbines in a year you would have to:

• Mine, transport and burn 72 million tonnes of coal, at a cost of €4,983 million, and emit 219.5 Mt of CO2, or• Extract, transport and burn 42.4 million cubic meters of gas, at a cost of €7,537 million, and emit 97.8 Mt of CO2.

EWEA is the voice of the wind industry, actively promoting wind power in Europe and worldwide. It has over 600 members, which are active in over 50 countries, making EWEA the world's largest and most powerful wind energy network.
